NOTE:
The HS-24 must be set for Code 3 horn when used with the sync module. Refer to Sync Module Installation
Instruction sheets SM (P83123), DSM (P83177) and Wheelock’s Power Supplies for additional information. If the HS-24 is
connected to a coded system the continuous horn setting must be used
Figure 3:

HS-24 Appliance has in-out wiring terminals that accept two #12 to #18 American Wire Gauge
(AWG) wires at each screw terminal. Strip leads 3/8” inches for connection to screw terminals.
2.
Break all in-out wire runs on supervised circuits or circuits in which supervision is used as shown
in Figure 3. The polarity shown in the wiring diagrams is for the operation of the appliances. The
polarity is reversed by the FACP during supervision.
MOUNTING OPTIONS:
CAUTION:
The following figures show the maximum number of field wires (conductors) that can enter the backbox used
with each mounting option. If these limits are exceeded, there may be insufficient space in the backbox to accommodate the
field wires and stresses from the wires could damage the product.
Although the limits shown for each mounting option comply with the National Electrical Code (NEC), Wheelock recommends
use of the largest backbox option shown and the use of approved stranded field wires, whenever possible, to provide additional
wiring room for easy installation and minimum stress on the product from wiring.
